Definitions
- the invention relates to a femoral component for a hip endoprosthesis according to the preamble of claim 1.
- femoral component has to be cleared too large in relation to the prosthesis socket in order to make room for the bone cement.
- the stem is inserted into the cleared femoral bed that has already been filled with bone cement.
- Precise and quiet storage during the polymerization process is quite problematic and, if handled improperly, can lead to non-uniform cement coat formation and locally excessive stress concentrations in the hardened bone cement.
- a generic femoral component is already from US 5,133,772 HACK ET AL. known.
- the bone cement is filled in through one or more internal channels which open from the prosthesis neck through the inside of the shaft into a peripheral groove.
- the cement application is too little targeted locally in the proximal area to achieve the most physiological possible load transfer to the femur.
- the internal channels lead to a mechanical weakening of the implant in the area of the cement ring to be applied, because the cannulation weakens the cross section of the prosthesis socket.
- the long and tortuous cannulation in the prosthesis limits the use of normal viscous bone cement to a very short phase of the polymerization. If this phase is exceeded, there is a risk of excessive frictional resistance of the bone cement to be applied in the channels - this can lead to a qualitative impairment of the polymerized proximal cement ring.
- the internal channels also carry the risk of clogging.
- the standard cemented systems result in a less targeted application of force to the femur than the load is applied over the entire but predominantly distal prosthesis socket and is therefore unphysiological. This can lead to proximal bone resorption and later instability of the prosthesis.
- the invention seeks to remedy this.
- the invention has for its object to provide a femoral component for a hip endoprosthesis which can be fixed proximally in the femur via a compact, homogeneous cement mantle zone, thereby achieving a largely physiological load distribution in the proximal shaft area and largely eliminating the risk of varusal tipping.
- the invention solves this problem with a femoral component which has the features of claim 1.
- the invention combines the advantages of cement anchoring, such as better primary stability due to the initial good positive locking, with the proximal anchoring and thus physiological stress on the femur.
- the fit accuracy of non-cemented systems can be achieved with the femoral component according to the invention, allowing minimal clearance of the femur.
- FIG. 1 shows a perspective illustration of the femoral component according to the invention.
- FIG. 2 shows a side view of the femoral component according to FIG. 1.
- the femoral component for a hip endoprosthesis shown in FIGS. 1 and 2 has a distal end 1 intended for insertion into the medullary cavity, a proximal shoulder part 2 with a neck 3, and a shaft part 4 with a longitudinal axis 5 lying between the shoulder part 2 and the end 1 and length L, as well as a peripheral circumferential groove 6, which is provided in the proximal third of the shaft part 4, which merges into the shoulder part 2.
- the groove 6 is connected to the proximal zone 8 of the shoulder part 2 via two or more channels 7 running in the direction of the longitudinal axis 5 on the surface of the shoulder part 2.
- 2 is an anterior lying channel 7 visible.
- a corresponding channel is also placed posteriorly.
- the channels 7 have an average cross-sectional area of 8 to 120 mm 2 , preferably 15 to 50 mm 2 .
- the groove 6 expediently has an average depth of 0.5 to 6.0 mm, preferably 1 to 4 mm, or 2 to 40% of the width of the shoulder part 2 measured in the medio-lateral direction.
- the average height of the groove 6 is in the direction of the longitudinal axis
- the volume of the groove 6 is expediently 500 to 10,000 mm 3 , preferably 2,000 to 6,000 mm 3 .
- the average cross section of the shaft part 4 in the region of the groove 6 is advantageously 50 to 500 mm 2 , preferably 100 to 300 mm 2 .
- the center of the groove 6 is at a distance of 60 to 250 mm, preferably 100 to 200 mm from the distal shaft end 1 and from 15 to 100 mm, preferably from 30 to 60 mm from the distal
- the proximal border 10 of the groove 6 has a medial measurement
- the proximal boundary 10 of the groove 6 has a distance of 5 to 50 mm, preferably 15 to 35 mm, to the distal boundary 11 of the proximal zone 8 of the shoulder section 2.
- the average cross section of the shaft part 4 in its distal third, including the end 1, is advantageously 25 to 120 mm 2 , preferably 40 to 80 mm 2 .
- non-continuous grooves or ribs 9 can be provided in the proximal third of the shaft part 4 which merges into the shoulder part 2.
- the advantage of these additional grooves or ribs 9 lies in the interlocking bond between prosthesis and femur that can be achieved thereby, in order to improve primary stability in the sense of a non-cemented prosthesis. This leads to a further macroscopic spongy anchoring (which acts in addition to the cement anchoring), which increases the torque resilience (rotation stability, rotation protection) of the prosthesis.
- the additional grooves or ribs 9 also result in additional guidance and thus an exact positional positioning of the prosthesis during the setting process.
- a microstructuring is provided which has an average roughness depth of 5 ⁇ m to 1000 ⁇ m, preferably of 10 ⁇ m to 600 ⁇ m. Because the whole If the proximal part is used to apply force from the implant to the bone and a proximal zone above the cement ring is provided for supporting and guiding tasks, an optimization of the bony growth behavior and thus a bony integration takes place in this zone in particular by means of a corresponding surface texture.
- This proximal half of the femoral component (without groove 6) is advantageously at least partially provided with a coating of a bioactive material, preferably hydroxylapatite.
- a bioactive material preferably hydroxylapatite.
- a ball head can be attached to the neck 3 in a known manner.
